Debian Security Advisory

DSA-1943-1 openldap openldap2.3 -- insufficient input validation

Date Reported:

02 Dec 2009

Affected Packages:

openldap, openldap2.3

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 553432.
In Mitre's CVE dictionary: CVE-2009-3767.

More information:

It was discovered that OpenLDAP, a free implementation of the Lightweight Directory Access Protocol, when OpenSSL is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

For the oldstable distribution (etch), this problem has been fixed in version 2.3.30-5+etch4 for openldap2.3.

For the stable distribution (lenny), this problem has been fixed in version 2.4.11-1+lenny1 for openldap.

For the testing distribution (squeeze), and the unstable distribution (sid), this problem has been fixed in version 2.4.17-2.1 for openldap.

We recommend that you upgrade your openldap2.3/openldap packages.

Fixed in:

Debian GNU/Linux 4.0 (etch)
